应变速率、温度及成分协同调控高速挤压镁合金的研究进展
Research Progress on Synergistic Regulation of Strain Rate,Temperature,and Composition in High-Speed Extruded Magnesium Alloys
摘要
Abstract
Extrusion forming is an important plastic processing method for magnesium alloys.However,the conventional extrusion speed of magnesium alloys is much lower than that of aluminum alloys,resulting in low production efficiency and high cost,which limits the large-scale application of extruded magnesium alloy profiles.High-speed extrusion technology provides a possibility for increasing the extrusion speed of magnesium alloys through effects such as adiabatic temperature rise,dynamic recrystallization(DRX)refinement,and supersaturated solid solution induced by high strain rates.Furthermore,the composition of magnesium alloys has a significant impact on their extrudability,and only some magnesium alloy systems are suitable for high-speed extrusion forming.This paper systematically reviews the synergistic regulation mechanisms of strain rate,temperature,and alloy composition on the microstructure and mechanical properties of high-speed extruded magnesium alloys,summarizes the current research progress,and prospects the future development directions,so as to promote the application of this technology in large-scale industry.关键词
